I've just received my copy in the mail - I'm sure this is a White Box game despite the lack of OGL and WB license. It's a good read with some odd bits missing - no overland movement rates for man beast or vehicle, a new ability table (from B/X) that isn't supported in the rules. But these are oversights, overall it's a good piece of work with the high points being the excellent monster section, random tables and fantastic artwork.

If anyone else has a copy I'd love to hear your thoughts and exchange an idea or two. I will almost certainly take this for a spin in early March with my group. The idea being that earth characters wake up in a cave on Barsoom following a near fatal tube crash. They will discover their latent Martian powers after a short while on the Red Planet.
